Subject: [PATCH 3.12 052/124] HID: do not bind to Microchip Pick16F1454

From: Kristian Evensen <kristian.evensen@...il.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit a8c8316b11594e616df641b4b19ec9da732f93df upstream.

The Microchip Pick16F1454 is exported as a HID device and is used by for
example the Yepkit YKUSH three-port switchable USB hub. However, it is not an
actual HID-device. On the Yepkit, it is used to power up/down the ports on the
hub. The HID driver should ignore this device.
